Fig. 4.

The mean and standard deviation of the 500 GO clustering enrichment scores of the sampled clusterings (selected motifs). GO clustering enrichment scores are averages of the x most enriched clusters, with here x = 25. The logarithm of the GO enrichment p-values is plotted against 100 values of α. We use the consensus clustering at α = 0.25 as the final combined clustering. To show the biological relevance of the selected motifs, the mean p-values achieved over 500 clustering iterations with randomly selected motifs (no preselection) and with random base strings (fake motifs) are also shown.
